BRANDT agitators power the drilling industry with high-quality, time-proven mechanical agitation. . Active mud system compartments such as solids removal sections, mud mixing sections, and slug pits—which need a higher shear force to produce immediate mixing—are another consideration in impeller sizing.
Centrifugal pumps are widely used in various industries for the transportation of fluids. One critical aspect of centrifugal pump operation is the calculation of total head, which is essential for selecting the right pump for a specific application. In this article, we will delve into the process of calculating total head, determining the Net Positive Suction Head (NPSH) available, and predicting pump efficiency through the calculation of specific speed.

Centrifugal Pump Head Calculation Formula
The total head of a centrifugal pump is the sum of the static head, velocity head, and friction head. The formula for calculating total head can be expressed as:
\[ Total Head = Static Head + Velocity Head + Friction Head \]
Where:
- Static Head: The vertical distance from the surface of the liquid in the suction tank to the centerline of the pump.
- Velocity Head: The kinetic energy of the fluid as it enters the impeller.
- Friction Head: The energy loss due to friction as the fluid passes through the pump and piping system.
